Product Code: L12TM3
​Type: Heavy-Duty Trench Mesh (High-Strength Configuration)
​Compliance: AS/NZS 4671 | ACRS Certified | ISO 1461 (Galvanized Option)

Technical Specifications:

Key Features:

1. ​Superior Load-Bearing Capacity​

   • ​12mm high-yield steel​ (500MPa tensile strength) delivers ​30% higher shear resistance​ vs. 11mm equivalents.
   • Optimized for AS 2870 Class H1 reactive soil conditions.

2. ​Precision Engineering​

   • Robotic welding ensures ​​±1.5mm dimensional tolerance​ and ​≥3,800N/mm² weld strength​ (AS/NZS 1554.3).
   • 3-wire configuration reduces on-site assembly time by ​65%​​ compared to manual rebar tying.

3. ​Enhanced Durability​

   • Hot-dip galvanized option provides ​75μm coating thickness​ (AS/NZS 4680) for coastal/marine environments.
   • Mill-scaled black steel version includes anti-corrosion inhibitor treatment.

4. ​Traceability & Compliance​

   • Laser-etched QR code links to digital ACRS certification and steel mill test reports.
   • Carbon-neutral manufacturing process (GBCA Green Star MAT-6 compliant).

Typical Applications:

• ​Civil Infrastructure:
  • Highway bridge abutment foundations
  • Retaining walls with >1.5m retained height
  • Railway underpass drainage trenches
• ​Heavy Commercial:
  • Multi-story building strip footings
  • Industrial warehouse column bases
  • Precast concrete culvert systems (1.5m+ spans)
• ​Utilities:
  • High-pressure pipeline trench reinforcement
  • Substation transformer plinths

Ordering Notes:

❗ ​Customization:

• Available in ​4.5m–12m lengths​ (minimum 40 units for non-standard sizes).
• Galvanized orders require ​21-day lead time.

❗ ​Logistics:

• Non-stackable bundles – requires flatbed transport with edge protectors.
• UV-stable nylon strapping prevents weather degradation during storage.

❗ ​Compatibility:

• Use with ARC ​TMC12200 trench clips​ (sold separately) for AS 3600-compliant lapping.
• Integrates with ​BCPT65 plastic chairs​ for 65mm concrete cover applications.
